Abstract
A shallow sea high-pressure small-caliber composite hose coupler comprises a coupler jacket, an O-shaped seal ring, a protective sleeve of an exhaust valve, the exhaust valve and a coupler core. The coupler jacket and the coupler core are of toothed structures, and the toothed structures are embedded into a composite hose through buckling, so enough strength and a certain air tightness are provided for the composite hose coupler. An annular groove is arranged on the coupler core and is contained in the O-shaped seal ring, and the O-shaped seal ring is closely contacted with the inner wall of the composite hose to generate deformation through buckling, so enough air tightness is provided for the composite hose coupler. The coupler well improves the buckling stability and the tightness of the hose, the expansion quantity is reduced, and the buckling damage to the hose is reduced. The internal diameter of the coupler after the buckling is 95 percent of that of the hose, so the influence of the coupler on the oil gas delivery quantity is greatly reduced, and the sphere penetration and wire cleaning of a pipeline and other operations are not interfered.
Description
Technical field
The utility model belongs to the innovation of ocean flexible pipe protective gear.
Background technique
It is the main mode that the modern marine flexible pipe is produced and constructed that the joint at flexible pipe two ends connects into the whole piece pipeline to the flexible pipe of segmentation, withholding of joint and flexible pipe just becomes the important ring that pipeline is produced, the joint mode of withholding in the past adopts simple outer button mode, and this method is only applicable to pipeline internal pressure environment.And under the condition of limited caliber, the raising of quantity delivered just means the raising of discharge pressure, and the raising of oil gas discharge pressure is had higher requirement to pipeline and being connected of joint.
Summary of the invention
The technical problem that the utility model solves provides the small-bore composite soft tube joint of shallow sea high pressure, traditional outer button can't guarantee the sealing under the high pressure, skeleton enhancement layer in the flexible pipe effectively is not connected with joint with stretch-resisting layer, cause flexible pipe under high pressure to extend, be out of shape, cause oil and gas leakage easily, even joint comes off.This need design a hose coupling, under the prerequisite of proof strength and sealing, changes the composite of flexible pipe dress into common metal material and is convenient to mounting flange or operation such as welds.The utility model proposes the joint of the small-bore composite soft tube of a kind of shallow sea high pressure.
The utility model technology contents is that high pressure small-bore composite soft tube joint in shallow sea comprises joint overcoat, O RunddichtringO, outlet valve protecting jacket, outlet valve, joint fuse.Design annular groove on the joint fuse, put into the O RunddichtringO,, make the O RunddichtringO closely contact and produce deformation, for the composite soft tube joint provides enough tightness with the composite soft tube inwall by the process of withholding.The dental structure of joint overcoat and joint fuse has replaced the coarse thread structure by closely-pitched gradual change dental structure, has increased the tooth number, has avoided the destruction of the internal pipe of joint and the generation that stress is concentrated.Joint overcoat front end designs for cavity structure, increases the outlet valve protecting jacket, by sealing thread outlet valve is installed in the outlet valve protecting jacket, guarantees that O RunddichtringO and composite soft tube are not destroyed by high temperature.
The beneficial effects of the utility model are, this joint has improved the stability of withholding and the sealing of flexible pipe well, and reducing of the amount of rising reduced to withhold the damage to flexible pipe.Joint internal diameter after withholding reaches 95% of inner diameter, has reduced the influence of joint to the oil gas quantity delivered widely, and does not hinder work such as pipeline through ball pipeline purging.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further.
Fig. 1 withholds joint structure for composite soft tube before withholding;
Fig. 2 withholds joint structure for withholding the back composite soft tube.
1-composite soft tube wherein; 2-joint overcoat; 3-O RunddichtringO; 4-joint fuse; 5-outlet valve; 6-outlet valve protecting jacket.
Embodiment
Withhold joint structure for composite soft tube before withholding among Fig. 1, O RunddichtringO 3 is put into the circular groove of joint fuse 4, by screw thread joint overcoat 2 and joint fuse 4 are grouped together, and carry out argon tungsten-arc welding at jointing and weld, to guarantee sealing, prevent that seawater from infiltrating from screw thread, in welding process, need with cold water cooling cooling, to guarantee that O RunddichtringO 3 is not destroyed by high temperature, will withhold joint at last and be inserted in flexible pipe 1, withhold ready.
Withhold joint structure for withholding the back composite soft tube among Fig. 2, withhold that the dental structure of joint overcoat 2 and joint fuse 4 is inlaid into composite soft tube 1 after finishing, for the composite soft tube joint provides enough intensity and certain tightness; Joint fuse 4 internal diameters increase makes O RunddichtringO 3 closely contact and produce deformation with composite soft tube 1 inwall, for the composite soft tube joint provides enough tightness; Punching on the joint overcoat 2 on cavity top; outlet valve protecting jacket 6 is put into cavity; and carry out argon tungsten-arc welding at jointing and weld; in welding process, need with cold water cooling cooling; to guarantee that O RunddichtringO 3 and composite soft tube 1 are not destroyed by high temperature, are installed in outlet valve 5 in the outlet valve protecting jacket 6 by sealing thread.
Claims (3)
1. the small-bore composite soft tube joint of shallow sea high pressure; form by joint overcoat, O RunddichtringO, outlet valve protecting jacket, outlet valve, joint fuse; it is characterized in that on the joint fuse, designing annular groove; put into the O RunddichtringO; by the process of withholding, make the O RunddichtringO closely contact and produce deformation with the composite soft tube inwall.
2. the small-bore composite soft tube joint of shallow sea according to claim 1 high pressure, its feature have replaced the coarse thread structure at the dental structure of joint overcoat and joint fuse by closely-pitched gradual change dental structure.
3. the small-bore composite soft tube joint of shallow sea according to claim 1 high pressure; its feature designs for cavity structure at joint overcoat front end; increase the outlet valve protecting jacket, outlet valve is installed in the outlet valve protecting jacket, guarantee that O RunddichtringO and composite soft tube are not destroyed by high temperature by sealing thread.
